Yes, Trapinch is a small, snapping pokemon which lives underground, whereas Vibrava is more like an insect, flying type pokemon. Flygon and Vibrava are pretty similar, but i was surprised when i found out they start off life as a Trapinch

Is it just me, or should Flygon be Salamence's name and Flygon have a different name? Bagon, Shelgon, Flygon. I mean, it just makes sense. Also, Bagon has been trying to learn to Fly so doesn't a name like FLYgon make sense?
